rube goldberg M31

Just getting started connecting my DSLR with my telescopes, and I think I could learn to like this. My son and I sat in the back yard taking this session with M31, and the equipment arrangement reads like a Rube Goldberg contraption.

We used my AT66 ED for imaging (64 shots, 30 secs each, unguided), and this telescope was piggybacked onto my Ultima-11's already-overloaded mount. Every breath of wind makes this arrangement move, but luckily, we had little wind on July 2-3, so the frames came out fine.

But 30 seconds was the maximum we could manage from the mount, as it's barely up to visual imaging, so anything longer constitutes pushing one's luck.

This was stacked and stretched in Nebulosity, and except for a bit of red gradient that I have to learn to get rid of (M31 was situated right above a neighborhood sodium vapor street lamp), things turned out pretty well. The moon was up, the wind kept threatening to shut us down, and high clouds periodically obscured most of the sky, but so far, so good!

Constructive comments and suggestions are appreciated. This is only my second full night of digital astrophotography, so I can use all the help I can get (well, that and a GEM, too!).
